BOX-COVERING MACHINE.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed May 6, 1912. Serial No. 695,368.

To all whom it may concern:

Be it known that I, EDWARD E. DAILEx, a citizen of the United States, and a resident of Needham Heights, in the county of Norfolk and Commonwealth of Massachusetts, have invented an Improvement in Box- Govering Machines, of which the follow ing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

My invention relates to machines for handling sheet material, being more particularly concerned with machines for applying an adhesive material to a strip of paper or cloth, and winding the strip about the sides of boxes or other articles.

My invention will be best understood by reference to the following description, when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings :F igure 1 is a side elevation of a box covering machine embodying my invention. Fig. 2 is a detail sectional view partly in elevation on lines 22 of Fig. 1. Fig. 3 is a detail section at an enlarged scale on line 33 of Fig. 1. Fig. 4 is a plan of the gluepan and adjacent devices. Fig. 5 is a detail section on line 55 of Fig. 1.

Referring to the drawings and to the embodiment of my invention which I have there shown for illustrative purposes, I have there shown a box covering machine having a suitable frame 5 for supporting the operative parts of the machine, and on this frame is mounted a suitable device for applying the glue or other adhesive material to the paper, cloth, or other sheet material, this device herein comprising a roll 6, receiving its supply of glue from a suitable reservoir 7, the roll for this purpose being partly submerged in the glue. A strip, or strips, 8 of sheet material may be fed from any suitable source of supply, such for example as a roll, or rolls, 9 across and in driving contact with the periphery of the glue roll 6 by any suitable means, such for example as a rotating form 10, the latter being herein suitably constructed to receive the sides of the box blank, and being mounted to rotate on a suitable head 11. This head may be adjustably mounted in any suitable manner, but since the head per 86 forms no part of my present invention, it will be unnecessary to further describe the same herein.

The rotating form 10 may be rotated by any suitable means, herein being driven by a pair of beveled gears 12 and 13, the former being secured to the shaft 14 of the form,

.and the latter being secured to a shaft 15.

The shaft 15 is driven by suitable means, such for example as a worm gear 16 meshing wlth a worm 17 secured to a driving shaft 18. This shaft carries a constantly rotating loose pulley 19, which may be driven from any suitable source of power not shown, and constitutes one member of a clutch. The other clutch member 20 is splined on the driving shaft 18, and is normally held out of driving engagement with the member 19 by a suitable spring 22 interposed between the said members. Mounted in suitable guides 23 and 2 1, is a clutchshifting rod 25, under the control of the operator through a treadle 26, treadle-rod 27 and bell-crank lever 28, having an arm 29 bearing against one end of the clutch shifting rod 25. The clutch-shifting rod is provided with suitable means for controlling the shiftable clutch member 20, herein con sisting of a member 30 secured to said rod and engaging said clutch member in such a manner as to force the latter against the tension of the spring 22 into driving engagement with the clutch member 19. Suitable means are provided for stopping the feeding motion of the feeding means by stopping the rotation of the driving shaft 18 when the clutch is disengaged, said means herein comprising a friction disk 31, secured to and driven by said shaft, and a non-rotating friction disk 32 carried by the clutchshifting rod 25. A suitable spring 33 is arranged to urge the friction disk 32 into engagement with the friction disk 31 simultaneously with the disengagement of the clutch members.

Interposed between the glue roll 6 and the rotating form 10 are suitable instrumentalities for severing the strip of paper, herein comprising a fixed knife 34: and a cooperating movable knife 35, actuated by suitable means, such for example as an arm or arms 36 secured to a rock-shaft 37. Secured to this rock shaft is a gear 38, meshing with a gear 39, secured to a rock shaft 40 journalcd in suitable bearings in a bracket 41 forming part of the frame of the machine. Secured to the rock shaft 40 is an arm 42, to which is connected the upper end of a rod 43, the lower end of said rod being pivotally connected to a cam lever 44 secured to a rockshaft 45. The cam lever 44 coijperates with a suitable cam 46, and for that purpose is herein provided with a protuberance 47 engaging the periphery of the cam, the latter being provided with a depression 48 of suitable depth and extent to allow the cam lever to drop at the proper time in the operation of the machine and actuate the movable knife 35 to cooperate with the stationary knife 34 to sever the strip of paper or other material. Secured to the rock-shaft 45 is an arm 49, to whichis secured one end of a suitable spring 50, the other end being secured to a suitable fixed point, as for example a pin 51 on the frame of the machine, this spring assisting in the downward movement of the knife 35 and its connected parts. The cam 46 is secured to a shaft 52 driven by a worm gear 53, also secured thereto and meshing with the worm 17. It will thus be seen that the knives are caused to operate to sever the paper at a pre-determined time in the operation of the machine.

Located beneath and preferably contacting with the arm 49 is an arm 54 secured to a rock-shaft 55, mounted in suitable bearings 56 and 57 on the frame of the machine. Secured to this rock-shaft is an arm 58 connected by suitable means, herein links 59 and 60 to a brake-shoe 61, engaging a brakedrum 62 secured to the shaft of the glue roll 6. The brakeshoe may, if desired, be provided with a suitable lining 68 of leather or other suitable material. The brake-shoe 61 may be constructed in any suitable manner, so as to normally remain out of engagement with the brake-drum 62, and for that purpose is herein made of resilient material, so that it is normally lifted from the brakedrum. It Will now be apparent that when the strip of material is being fed by the rotation of the form 10, the strip will be fed across and in driving contact with the glue roll 6, so as to rotate the latter, and therefore apply the glue or other adhesive matter to the strip of paper. But when the rotation ofthe form ceases, and the strip of material is severed by the knives, the rotation of the "glue roll will be instantly and automatically stopped by the action of the brake, so as to prevent over-travel due to the inertia of the drum. This device therefore overcomes one very serious fault in machines of this class heretofore, namely, the over-travel of the glue roll, which results in the paper or other material continuing to feed forward under the influence of the roll and form a slack between the roll and the knives. This is very undesirable for the reason that it spoils the tension on the material, as well as wasting the glue or other adhesive material, and often causes the strip to disengage from the roll and thus cause portions of the strip to remain uncoated.

There may be provided any usual or de 'sired means for guiding the strip or strips of material, and stripping or scraping oil the excess adhesive material therefrom. For this purpose, I have shown a usual guide (34, adapted to guide the strip or strips 8 of material from the supply roll or rolls 9 to the glue roll 6, a usual guide and. stripper 65 adapted to guide the strips and remove the excess glue so that the latter will return to the reservoir 7, an auxiliary stripper 66, with a receiver 67 for the drippings, and a guide 68. These parts are all of the usual construction, and act in the usual and well-known manner to cause the coated strips to be delivered to the winding form tempered, or partially dried, so as to properly adhere to the box blank.

While I have herein shown. and described one form of my invention for illustrative purposes, and have disclosed and discusser in detail the construction and arrangement incidental to one specific application thereof, it is to be understood that the invention is limited neither to the specific embodiment herein shown nor to the more details or relative arrangement of parts, but that extensive deviations from the illustrated form or embodiment of the invention may be made, without departing from the principles thereof.

Having thus described one embodiment of my invention, what I claim and desire by Letters Patent to secure is:
